As AI writing instruments maintain getting higher, we’re seeing a brand new wave of options pop up: not simply instruments to generate content material, however for making that content material sound much less machine-like.
One of many latest battlegrounds? AI humanizers.
Undetectable AI constructed its title round this concept. However now Grammarly—as soon as simply your go-to grammar checker—has stepped into the ring with its personal take: an AI humanizer that rewrites robotic-sounding content material into one thing extra pure.
So how do the 2 stack up?
Earlier than we get into the head-to-head, let’s break down what every software truly does.
What’s Undetectable AI?
Undetectable AI is a rewriting software constructed to make AI-generated textual content sound extra human. It doesn’t simply repair tone or grammar. It particularly targets the patterns that AI detectors search for—like predictable phrasing, formal over-politeness, or flat transitions—and reworks them into one thing extra human, much less detectable.
It’s in style with college students, freelancers, and anybody who needs to write down sooner utilizing AI with out sounding like a bot. One standout function is the Writing Model Replicator, which not solely humanizes content material but additionally tries to imitate your personal voice.
What’s Grammarly?
Grammarly began out as a grammar and spelling checker—a software you used to scrub up your writing after the very fact. However in the previous couple of years, it’s developed into a wider writing assistant. Now, it affords AI-powered recommendations for readability, tone, and construction, and even generates content material from scratch.
Its newest function? An AI humanizer.
Grammarly’s model of a humanizer rewrites stiff or robotic textual content (often from ChatGPT or related instruments) to sound extra pure. It leans closely into Grammarly’s present tone recommendations and tries to maintain the content material polished, however extra readable.
In principle, it shares the identical purpose as Undetectable AI: smoother, much less detectable writing. However the way in which every software goes about it—and who it’s actually constructed for—makes all of the distinction.

What’s Subsequent?
So right here’s what we discovered: Undetectable AI efficiently bypassed AI detectors 60% of the time. Grammarly’s humanizer? Zero.
That doesn’t imply Grammarly’s software is ineffective. It nonetheless does a stable job (higher than Undetectable AI) cleansing up awkward AI writing, particularly in case your purpose is healthier tone or stream. However in the case of truly dodging detection? It doesn’t maintain up.
Undetectable AI, alternatively, is clearly constructed with evasion in thoughts. It doesn’t simply clean issues out—it rewrites with goal. That makes an enormous distinction while you’re making an attempt to remain beneath the radar.
In fact, there’s at all times an moral dialog available about instruments like this. However in case you’re writing authentic content material and simply need it to sound such as you—not a language mannequin—then instruments like Undetectable AI provide a reasonably compelling choice.
On the finish of the day, each instruments have worth. But when the purpose is to sound human and keep undetected, one is clearly constructed for that job. The opposite… nonetheless has some catching as much as do.
